The <tspan> SVG element defines a subtext within a <text> element or another <tspan> element. It allows for adjustment of the style and/or position of that subtext as needed.

The Set object lets you store unique values of any type, whether primitive values or object references.

The <feComposite> SVG filter primitive performs the combination of two input images pixel-wise in image space using one of the Porter-Duff compositing operations: over, in, atop, out, xor, lighter, or arithmetic.

The <feFuncA> SVG filter primitive defines the transfer function for the alpha component of the input graphic of its parent <feComponentTransfer> element.

The <svg> SVG element is a container that defines a new coordinate system and viewport. It is used as the outermost element of SVG documents, but it can also be used to embed an SVG fragment inside an SVG or HTML document.

The <image> SVG element includes images inside SVG documents. It can display raster image files or other SVG files.

The function declaration creates a binding of a new function to a given name.

import.meta.resolve() is a built-in function defined on the import.meta object of a JavaScript module that resolves a module specifier to a URL using the current module's URL as base.

The Float16Array typed array represents an array of 16-bit floating point numbers in the platform byte order. If control over byte order is needed, use DataView instead. The contents are initialized to 0 unless initialization data is explicitly provided. Once established, you can reference elements in the array using the object's methods, or using standard array index syntax (that is, using bracket notation).
